About 6 months ago or so, Hell and Earth both got...a bit of a shock, let's say. After the fight between the Hazbin Hotel and Heaven's Exorcist angels, the seraphim and archangels had decided that killing demon sinners wasn't enough. They had to eliminate humans too.
Lucifer had decided he was having none of this, (see here- Charlie had decided she was having none of this and asked her dad to do something about it-) and against God's orders, he opened the gates of Hell in order to warn humankind of what was going to happen. It's halfway to the Extermination, and a pretty good fighting force is being instated- cooperations between Earth and Hell are shaky at best, but necessary if anyone wants to survive this.
Meanwhile, you? You've been living it up. More than usual, at the very least. You were already prominent in the human world, but now you're prominent in both worlds.
A popular musician, you'd been playing at both Earth venues and Hell venues. Raking in cash and fans alike, you were practically bathing in glory. You'd also just got a sponsorship deal from The Vees- three of Hell's most powerful Overlords.
You liked them a lot- Vox was a goofball pretending to be intimidating most of the time, Val was mostly horny but once you got to know him, was a definite movie buff with a penchant for noir films and spaghetti westerns above all else, Velvette was a fashionista a step above the rest, and while she had a team of designers, she preferred to design certain things herself.
Tonight, they were supposed to be bringing their 'friends' (heavy emphasis on the quotations there), from the Hotel, to see your show. You could see them lined up in the front-row seats-
Vox with his hands behind his head, talking animatedly about your show to Charlie, as Val sat back with Angel whispering into his ear, every so often widening his eyes and making a whispered statement back, while Velvette chatted with Vaggie. Husk was leaning away from Alastor, and every time the deer demon attempted to speak, Vox glared at him but said nothing. This would be....fun.
